General Administrative Information

TCAM Allocation

TCAM Allocation
Cisco 500 Series Stackable Managed Switch Administration Guide
• Clear Startup Configuration File—Check to clear the configuration on the
switch for the next time it boots up.
• Reboot—Reboots the switch. Since any unsaved information in the Running
Configuration is discarded when the switch is rebooted, you must click Save
in the upper-right corner of any window to preserve current configuration
across the boot process. If the Save option is not displayed, the Running
Configuration matches the Startup Configuration and no action is necessary.
• Reboot to Factory Defaults—Reboots the switch by using the factory
default configuration. This process erases the Startup Configuration file and
the backup configuration file. The stack unit ID is set to auto. The system
mode is set to Layer 2 and any settings that are not saved to another file are
cleared when this action is selected. The mirror configuration file is not
deleted when restoring to factory default.
If the device is in Native Stacking mode, this button restores factory
NOTE
defaults on the entire stack.
Clearing the Startup Configuration File and Rebooting is not the same
NOTE
as Rebooting to Factory Defaults. Rebooting to Factory Defaults is more
intrusive.
TCAM allocation is handled differently in Sx500 and SG500X devices, as follows:
• Sx500: TCAM allocations can be modified in the IP TCAM Allocation
Settings page when these devices are in Layer 3 system mode (see
Allocation Settings
SG500X: TCAM allocations can be viewed in the IP TCAM Allocation
NOTE
page (see TCAM Allocation
TCAM Allocation Settings Page
TCAM entries are divided into the following groups:
• IP Entries—TCAM entries reserved for IPv4 static routes, IP interfaces, and
IP hosts. Each type generates the following number of TCAM entries:
- IPv4 Static Routes—One entry per route
- IP Interface—Two entries per interface
